Question

Identify the correct representation of reaction occurring during chloralkali process

विकल्प

• `2"NaCl"("l") + 2"H"_2"O"("l") -> 2"NaOH"("l") + "Cl"_2("g") + "H"_2("g")`

• `2"NaCl"("aq") + 2"H"_2"O"("aq") -> 2"NaOH"("aq") + "Cl"_2("g") + "H"_2("g")`

• `2"NaCl"("aq")  + 2"H"_2"O"("l") -> 2"NaOH"("aq") + "Cl"_2("aq") + "H"
  _2("aq")`

• `2"NaCl"("aq") + 2"H"_2"O"("l") -> 2"NaOH"("aq") + "Cl"_2("g") + "H"_2("g")`

Answer 1

`2"NaCl"("aq") + 2"H"_2"O"("l") -> 2"NaOH"("aq") + "Cl"_2("g") + "H"_2("g")`

Explanation - 

It is the correct answer since the physical states of all the species involved are correct.
